I had to do this once on my 2000 Sabre. I tried to do it the way Basscat reccomends but had little success. I finally pulled out all the batteries and trays along with oil resevoir. Then I took the fuel tank loose and slid it backwards. Its easier if you run most of the gas out first. I ended up replacing everything while I was under there. Bilge pump, aerator pump and livewell valve. Then just put everything back being sure to put silicone anywhere you screw something down. Hope this helps. Sent from my SAMSUNG-SM-G935A using Tapatalk
